NFC ring witg tag in car to turn on bluetooth

Hey guys, I had a idea but not sure how to implement it. I want to get an nfc resder and put it in my car. Then when i get my the car i can use my ring with it to then tell my phone to turn on bluetooth and open spotify. This would be cool becsuse then I woulsnt even have to take my phone out of my pocket to use with an nfc tag. Instead i could use the nfc ring to do it. The lart im having trouble with is telling my phone to do the task from the reader after it comes in contact with the ring. Any suggestions?
